Operating instructions: Alarm
1.
Acknowledge the alarm.
2.
Check whether the alarm indicates high or low pressure. If the
indicated pressure
is correct,
can
be a malfunction to
the alarm system or the pressure has returned to normal operating pressure.
3.
If the pressure is not correct: Check

Operation
and Maintenance
The
line
pressure regulator must be exercised annually and tested for safety. If no abnormal inertia,
leakage or malfunction is detected, the device is approved for another year. In the event of a leak,
replace the O-rings at the connection or valve body, after which a new safety test takes place. Safety
testing takes place in accordance with national standard SIS HB 370.
Note that oil, grease and other contaminants must not come into contact with the product.
Regulators and safety valves can be serviced or replaced without interruption, by isolating the circuit to
be serviced with the shut-off valves. Note that during service during operation, a circuit must always be
kept open.
At annual safety test:
• The safety valves are checked to open at the set pressure. Also test the valve by pulling the relief
device on the side of the valve.
• The
pressure gauge
must be checked to show the correct pressure.
• O-rings are replaced if necessary.
• The function of the gas outlets must be tested.
After maintenance and service, the system must be leak tested. This is done by
pressurizing
the
system and then checking that the system is
leak
tight with the help of leak spray.
Settings, repairs and service must be performed by Qmt-tech technicians or by technicians authorized
by this company.
At product end, the unit is
returned to an authorized recycling company.
